A line with a slope of -2 passes thru the point (4,7)
Tpy6a [65]

Answer:

y - 7 = -2(x - 4)

Step-by-step explanation:

We are asked to write the equation of a line in point slope form

Step 1 : find slope

We are given the slope to be -2

Slope m = -2

Step 2: substitute m into point slope form

y - y_1 = m( x - x_1)

y - y_1 = -2 ( x - x _1)

Step 3: substitute the point into the equation

y - y_1 = -2( x - x _1)

( 4 , 7)

x_1 = 4

y_1 = 7

y - 7 = -2( x - 4)

We don't need to open the bracket because we are asked to write the equation in a point slope form

The area of a rectangular wall of a barn is 45 square feet. Its length is 12 feet longer than the width. Find the length and wid
ValentinkaMS [17]

Answer:

Mark as brainliest

Step-by-step explanation:

by using the formula for area:  A= L x W  substitute in what you know:   A = 54  , the length in terms of the width so use

 

L=12 + 2W.

 

Now when everything is plugged in you now have:  54 = (12 + 2W) x W  

 

Then use the Distributive Property to simplify:   54 = 12W + 2W2

 

Since you know have a quadratic to solve get it in the form  ax2+bx + c = 0 so that you can solve it:

 

You do this by subtracting 54 from both sides and putting the 2W2 first so now it looks like this:

 

2W2 + 12W -54 = 0

 

Using the quadratic formula where a =2, b = 12, and c = -54.

 

Find b2-4ac which is the discriminant:

 

(12)2-4*2*(-54)=576

 

Take the square root of 576= 24

 

Now substitute the rest of the values into the Quadratic Formula:

 

It will look something like this:   W = (-b plus or minus the square root of the discriminant)/2a

 

The two possible answers are:    

 

W = (-12 + 24)/4      and  W = (-12 - 24)/4

 

W = 12/4= 3            and W = -36/4= -9     (This second answer isn't possible because length can't be negative)

 

So the answer is:

 

Width = 3 feet        Length = 12 + 2W = 12 + 2*3= 12 + 6 = 18 feet

 

This checks because A = L x W     and  54 = 18 x 3

Which relation is not a function?
velikii [3]

Answer:

D.

Step-by-step explanation:

That would be D because there is a repetition of x = -6.

-6 maps to -6, 5 and -5 which is not allowed in a function.

Functions can be one-to-one or many-to-one but not one-to-many.
